SHK Pipes and fittings are produced from Polypropylene Random Copolymer Type 3 as raw material having low melt flow rate, high molecular weight and good flexibility.
This raw material is recommended for the production of pressure pipes including potable water transfer lines, hot and cold water transfer lines, floor heating and also for chemical industry application. Good long term pressure resistance and easy processing and installation technique give cold and hot water systems made of PP-R pipes an advantage as an alternative to the traditional systems.
Polypropylene Random Copolymer Type 3 corresponds to German DIN standards.
(a) DIN 8077 Pipe Dimensions
(b) DIN 8078 Pipes General Quality Requirements and Testing
(c) DIN 16962 Pipe Joins and Components for Pressure Pipes of Polypropylene
As per IS : 15801 & DIN 8077 : 1999-07 Wall Thickness and Mass Corresponding to Different Pipe Sizes
